Just picked up an Encad T200, with no cartrigdes...

Where is the cheapest place to get cartridges for an Encad t200?

Anybody have any old color carts, even empty, that you didn't throw out yet?. I'm only going to be printing B&W plans, But would like some 'dummy" color carts to stick in so the black cart I just got will work. I really don't want to spend the $200+ for carts that I won't use.. I will obviously pay shipping... ( 3 old B&W carts would work also)

Thanks in advance
